RECUMBENT CHAIR.

Specification of Letters Patent No. 21,320, dated August 31, 1858.

To all whom it may concern:

Be it known thatI, DAVID BUzzELr., of

Charlestown, in the county of Middlesex and State of Massachusetts, haveinvented a new and useful or' Improved Recumbent Chair; and I do herebydeclare that the same is fully described and represented in thefollowing specification and the accompanying drawings, which make partof the same.

Of such drawings, Figure l, denotes a side elevation of such chair. Fig.2, a vertical and centralsection of it. Fig. 3, a vertical sectionexhibiting the application and arrangement of a lever and two notchedcams to one end of the seat frame, and to the back and the leg rest.Fig. 4, is a section of the chair such being taken through the seat, itscorner su ports, the back, the leg rest and the seat ame.

In this chair what I term the seat frame is shown at A, as constructed`of two leg portions a, a, each of which has two legs b, b, connected bybars c, c, and in a manner to enable such seat frame to receive andsupport the operative or movable parts of the chair. This seat framealso carries the two arm rests CZ, cl, which with it are stationaryrelatively to the back B, the seat C, and the leg rest D. The back B,turns in the seat frame A, and on fulcra or journals or the equivalentsthereof the axial position of which is shown at e,'in Fig. 3. In asimilar manner is the leg rest D, applied to the seat frame A, so as toswing or turn on journals or their equivalents, the axial position ofsuch being shown at f. The said fulcra of the back and the leg rest areshown at e e and f', f', in Fig. 5, which is a horizontal section of thechair and is taken through them.

Alongside of the inner vertical surface of each portion a, of the seatframe A, a lever E, is arranged and so as to be capable of being turnedin a vertical plane on a fulcrum g, supported by the seat frame anddisposed atabout the middle part of the said lever. This lever at itsfront end may carry a friction roller h, or a projection to enter andwork in the recess z', of a notched cam or recessed plate F, formed asshown in Fig. 3, and fastened to the leg rest D. The rear end of thelever E, operates in connec tion with another recessed cam or plate G,which is attached to the back B, and carries a friction roller lo,arranged at the lower I part of the recess Z, of such plate Gr, as

shown in Fig. 3. The lever enters the recess which should be so formedas to cause the rlever to be moved on its fulcrum when ever the back isturned forward or backward. By pressing on the back B, in a manner tocause it to turn downward on its fulcra, the two levers E, E, will be somoved as to cause the leg rest to be moved outward or so turned on itsfulcra as to approach a horizontal position. The seat C, is supported bythe back and the leg rest and has journals m, m, m, m, extended from itssides at or near its corners, into the back and the leg rest, the axialpositions of such journals being shown at m, m', in Fig. 3,. The chairso made is to be upholstered in a proper manner, and its leg rest is tobe furnished with a foot rest a, extended from it as shown in thedrawings.

The object I have had in view in the invention of this chair has been toenable a person while sitting in it to easily operate the leg rest andthe back, by slight pressure against the foot rest of the leg rest. Bypressing his feet against the foot rest and at the same time lifting hislegs the said person can with great ease not only raise the leg rest upto any desirable inclination to the horizon but will at the same timecorrespondingly decline the back, and these parts will easily maintainany such position as long as the same may be agreeable to the sitter. Alittle downward pressure of the legs on the leg rest will suffice todepress the same and bring the back forward. The seat moves with theback and the leg rest and contributes by the weight of the sitters bodyto facilitate the operation of moving the back and the leg rest.

The particular advantage of this chair over many other recumbent chairsis to be found in the ease by which it can be operated. This renders itgreatly useful to invalids.

I am aware that it is not new to make a recumbent chair in such mannerthat the back when moved rearward shall throw up an apron or leg rest,such `having been accomplished by applying the leg rest to two leversand connecting the said levers to the back by jointed arm rests, suchbeing represented in the patent granted by the United States Governmentto J. G. Holmes on September 4, 1844. My chair or. the mechanism foroperating its back and leg restdiffers essentially in construction,arrangement and application from that of the said Holmes, as the armrests of 'my chair are stationary while in the said Holmes chair theyare movable and constitute jointed connections of the back and leg rest.

My present invention diiers materially from the arrangement andapplication of a triarmed lever to the back and front rest-s of a chairas described in my Patent No. 19910 of United States patents', for inthis latter the lever extends above the seat and is arranged againsttheinside surfaces of the arm rest and is connected to the back by a linkor connecting` rod, while in my present invention the lever is arrangedbelow the top of the seat and below the arm rest and is applied to theback and the leg rest by means of notched cams such as hereinbeforedescribed, one set of such notched 20 DAVID BUZZELL,
